Epigenetics - the sins of the father and the ten commandments

Exodus 20:5 is a verse from the Bible that is often interpreted as God punishing the children for the sins of their fathers. However, there is a growing body of scientific evidence that suggests that this verse may be referring to epigenetics, which is the study of how changes in gene expression can be inherited from parent to child.

Epigenetic changes are caused by environmental factors, such as stress, diet, and exposure to toxins. These changes can affect how genes are expressed, even if the DNA sequence itself does not change. Epigenetic changes can be passed down from parent to child, and they can have a significant impact on the health and well-being of the offspring.

For example, studies have shown that children of Holocaust survivors are more likely to suffer from anxiety and depression. This is thought to be due to epigenetic changes that were passed down from their parents, who experienced extreme stress during the Holocaust.

The evidence suggests that Exodus 20:5 may be referring to epigenetics. God is not punishing the children for the sins of their fathers. Rather, he is warning them about the dangers of environmental factors that can have a negative impact on their health and well-being as well as following the ten commandments for healthy living.

It is important to note that epigenetic changes are not always negative. Some epigenetic changes can be beneficial, such as those that protect against disease. However, it is important to be aware of the potential negative effects of environmental factors, and to take steps to protect yourself and your children from these risks.

Here are some tips for protecting yourself and your children from the negative effects of epigenetics:

• Eat a healthy diet. Eating a healthy diet can help to reduce stress and improve your overall health.

• Exercise regularly. Exercise is another great way to reduce stress and improve your health.

• Avoid toxins. Exposure to toxins can damage your DNA and lead to epigenetic changes. Try to avoid exposure to toxins as much as possible.

• Manage stress. Stress can lead to epigenetic changes. Find healthy ways to manage stress, such as exercise, relaxation techniques, or counseling.

By following these tips, you can help to protect yourself and your children from the negative effects of epigenetics.

The article "Epigenetics: The sins of the father" by Virginia C. Hughes, published in Nature in 2014, explores the emerging field of epigenetics and its implications for human health and behavior. Epigenetics is the study of changes in gene expression that are not caused by changes in the DNA sequence itself. These changes can be caused by environmental factors, such as diet, stress, and exposure to toxins, and they can be passed down from parents to offspring.

Hughes begins by describing a study in which mice were exposed to a frightening smell while they were still embryos. The mice that were exposed to the smell developed a fear of the smell that was passed down to their offspring, even though the offspring had never been exposed to the smell themselves. This suggests that the experience of the father can epigenetically alter the DNA of his sperm, and that these changes can be transmitted to the offspring.

Hughes goes on to discuss other studies that have found evidence of epigenetic inheritance in humans. For example, one study found that children who were born to mothers who were exposed to famine during pregnancy were more likely to be obese as adults. This suggests that the experience of the mother during pregnancy can epigenetically alter the DNA of her offspring, and that these changes can have a lasting impact on health.

Hughes concludes by discussing the implications of epigenetics for human health and behavior. She argues that epigenetics could be used to develop new treatments for diseases such as cancer and obesity. She also argues that epigenetics could be used to understand the links between environmental factors and human behavior, such as the link between childhood trauma and adult mental illness.

The field of epigenetics is still in its early stages, but it has the potential to revolutionize our understanding of human health and behavior. Hughes's article provides a good overview of this emerging field and its potential implications.

Here are some additional thoughts on the article:

• The idea that epigenetic changes can be passed down from parents to offspring is still controversial, but it is gaining increasing support from scientific research.

• Epigenetic changes can be caused by a variety of environmental factors, including diet, stress, and exposure to toxins.

• Epigenetic changes can have a lasting impact on health and behavior.

• Epigenetic research has the potential to develop new treatments for diseases and to better understand the links between environmental factors and human behavior.

Epigenetics: The sins of the father - Nature https://www.nature.com/articles/5201567

When Brian Dias became a father last October, he was, like any new parent, mindful of the enormous responsibility that lay before him. From that moment on, every choice he made could affect his newborn son's physical and psychological development. But, unlike most new parents, Dias was also aware of the influence of his past experiences — not to mention those of his parents, his grandparents and beyond.

Where one's ancestors lived, or how much they valued education, can clearly have effects that pass down through the generations. But what about the legacy of their health: whether they smoked, endured famine or fought in a war?

As a postdoc in Kerry Ressler's laboratory at Emory University in Atlanta, Georgia, Dias had spent much of the two years before his son's birth studying these kinds of questions in mice. Specifically, he looked at how fear associated with a particular smell affects the animals and leaves an imprint on the brains of their descendants.

Dias had been exposing male mice to acetophenone — a chemical with a sweet, almond-like smell — and then giving them a mild foot shock. After being exposed to this treatment five times a day for three days, the mice became reliably fearful, freezing in the presence of acetophenone even when they received no shock.

Ten days later, Dias allowed the mice to mate with unexposed females. When their young grew up, many of the animals were more sensitive to acetophenone than to other odours, and more likely to be startled by an unexpected noise during exposure to the smell. Their offspring — the 'grandchildren' of the mice trained to fear the smell — were also jumpier in the presence of acetophenone

this hereditary transmission of environmental information was the result of epigenetics — chemical changes to the genome that affect how DNA is packaged and expressed without altering its sequence.

The subject remains controversial, in part because it harks back to the discredited theories of Jean-Baptiste Lamarck, a nineteenth-century French biologist who proposed that organisms pass down acquired traits to future generations

To many modern biologists, that's “scary-sounding”, says Oliver Rando, a molecular biologist at the University of Massachusetts Medical School in Worcester, whose work suggests that such inheritance does indeed happen in animals3

If it is true, he says, “Why hasn't this been obvious to all the brilliant researchers in the past hundred years of genetics?”.

The epigenetics revolution hit in the early 2000s, when scientists began reporting that environmental factors — everything from neglectful mothering and child abuse to a high-fat diet and air pollution — can influence the addition or removal of chemical tags on DNA that turn genes on and off. This idea of an environmentally responsive genome still stirs debate
